ROBERT ADLEB, OF ST. PAUL, MINNESOTA ANTI-WASHOUT DEVICE FOR ROADWAYS Application filed May 10, 1930. Serial No. 451,301.

In the constructionof roadways, after the foundation or grade has been formed, it is common practice to allowthe soil to settle for a period of a year or more before the final hardsurface is applied. During this period for settling use of the road is frequently permitted and heretofore the washing away of the shoulders, particularly on inclined portions of the road, has caused much. trouble and expense. The resulting washouts often necessitate re-forming a large 'part'of the shoulders and even more central portions of the road grade are afiected.

It is the object of this invention to provide simple and inexpensive means for protecting the shoulders of roadways by eliminating much of such washing away of the shouldersland at the same time to permit the use of the grade where desirable or necessary without danger to the users or to cattle that may cross the road grade.

The invention will be best understood by reference to the accompanying drawings in which Figure 1 is a perspective view showing two sections of my device mounted on a road grade; Fig. 2 is a transverse section through a typical road grade showing the location of the devices thereon; Fig. 3 is a detail, perspective view of one of the clips for use at the joints between sections; Fig. 4 is a front view of one of the joints; Fig. 5 is a section taken on the line 5-5 of Fig. 4; Fig. 6 is a front view of an alternate arrangement ofa joint and Fig. 7 is a section'taken on the line 7- 7 of Fig. 6.

My device has a series of metal strips, two of which are indicated by the numerals 8 and 9 in the drawings. The strips are formed from heavy gauge sheet metal (prefera'bly about 18 to 20 gauge) and are held in upright position by stakes or pins 10 driven into the earth 11. A lower portion 12 of.

each strip is adapted to be pressed or otherwise imbedded in the earth 11. Above the portion 12 is a corrugation 13, and extending above the corrugation is a normally vertical portion 14. The portion 14 is offset laterally from the vertical plane of the portion 12 and is formed at its upper edge with a laterally extending flange 15. Perforations 16 in the flange 15 and in the corrugation 13 are provided to receive the pins 10. The upper ends of said pins are preferably bent outward to positively engage the flange 15 when in use. 1

The sections 8 and 9 are formed to be connected end to end and each has a notch 17 cut in its upper edge to receive the flange 15 on the adjacent section'and to permit overlapping of one section with another. A perforation 16a is provided beneath the notch 17 to receive one of the pins, such as the pin 10a, at the junction of the adjacent sections. A clip 18 (Figs.- 3 to 7 inclusive) is provided to strengthen the joint. This clip has a perforation 19 and a flange or bead 20 is formed along its upper edge, the perforation 19 being provided for the pin 10a at the joint.- The head 20 is turned under far enough to impinge against the pin and force the clip firmly against the'inner surface of the adjoining ends of the sections 8 and 9. The clip is constructed from resilient sheet metal which is sprung to grip the adjacent sections against the pin, as indicated in Figs. 5 and 7.

In use, the devices are positioned longitudinally of the shoulders and preferably along the sides of the main roadway and spaced 3. short distance from the outer edges of the shoulders, as indicated in Fig. 2. The device is particularly useful where there is a longitudinal slope to the road. Where so used, the device constitutes a baflie for the surface water which is forced to run along the concave side of the corrugation 13 until it reaches a suitable outlet, as at the bottom of-the slope.

and reinforce the devices by placing a small amount of earth along the outer faces, as indicated by the dotted lines 21 of Fig. 2. Later, when the finished orhard surface 22, of concrete or other material, is formed the devices may be covered and left in place or removed, if desired. In any event, eflicient protection against transverse channeling and washin away of the shoulders is afforded.

The orm of joint illustrated, ermits the lap of the adjoining sections to e made on either side depending on the direction of the slope. Thus the end formed with the notch 17 may be placed on the inner surface of the adjoining section, as shown in Figs. 6 and 7, or on the outer surface, as shown in Figs. 4 and 5. Where it is placed on the inner surface, the clip 18 has an important functionin pressing the strip beneath the notch into contact with the inner surface of the overlapping section, as shown in Fig. 7 Where the lap is made on the opposite side, as shown in Fig. 5, the clip 18 is not so essential but strengthens the joint and gives a neater appearance than the device would have without a clip. It will be evident that the rounded upper extremities of the metal strips and pins practically eliminate danger of injury to users or to cattle that may cross the right-of-way.

Having described my invention what I claim as new and desire to protect by Letters Patent is: v

1. An anti-washout device for roadways or the like comprising, a sheet metal member adapted to be secured in upright position, longitudinally of the road grade and having a lower portion formed to be imbedded in the road, a laterally bent flange extending along the upper edge of said member and means for retaining said member in upright position with its upper portion above the road grade to direct water longitudinally of the road.

2. An anti-washout device for roadways comprising, a long, narrow strip of sheet metal, adapted to be secured upon the surface of the road grade, longitudinally thereof, and having a bend located at the surface of the ground and imperforate portions adjacent to said bend, and means for retaining said strip in upright position to direct surface Water longitudinally of the road. a

3. An anti-washout device for the shoulders of roadways or the like, comprising, rigid metal stripsadapted to be secured end to end alongthe shoulder of the road, a bend extending longitudinally of .said strips at the surface of the roadway, the portions of said strip adjacent to said bend being imperforate,

and the upper portion of said strips being formed to engage supporting members above the road grade, laterally bent flanges along the upper edges of said strips and supporting members adapted to be driven into the road grade for retaining said strips in upright position.

4. An anti-washout device for the shoulders of roadways, or the like, comprising, rigid metal strips adapted to be secured end to end along the shoulder of the road, the upper portion of said strips being perforated to receive supporting members, supporting members adapted to be inserted in said perforations and to be driven into the road for retaining said strips in upright position and with their upper portions projecting above the grade and longitudinally extending, lIllperforate channels formed beneath said perforations to aflord a continuous longitudinal bafile for surface water.

5.
